Re: [D] [Question] Bundle-specific Python Path Isolation in Airflow 3.x Git Bundles [airflow]

GitHub user jherrmannNetfonds added a comment to the discussion: [Question] Bundle-specific Python Path Isolation in Airflow 3.x Git Bundles

I had the same issue and tried to fix this by modifying the python path. But the issue is that the DAG processor probes `PYTHONPATH` directories during startup before the DAG bundle git checkout finishes. Python caches those paths as empty (`None` in `sys.path_importer_cache`). The cache is never invalidated, so later imports fail even though the files are now there.
My workaround for now is to call `importlib.invalidate_caches()` in one DAG to force Python to re-scan the directories.
